Siemens 8WD4 300-1AB Red Pilot Indicator Light

Red flashing light element for Siemens SIRIUS 8WD4 signaling columns, designed to mount in a 70 mm diameter signaling tower and serve as a clear visual indicator in industrial automation. The 8WD4 300-1AB module is sold as the light element (without an internal light source), meant to be paired with a compatible housing; it specifies a 12–230 V AC/DC operating range and uses a BA15d base, aligning with Siemens' standard 8WD4 light-element form factor. This modular element is part of the SIRIUS 8WD4 signaling column family, enabling fast recognition of machine status, alarms, or process steps in production lines and control panels. Its rugged construction and standard dimensions support reliable operation in harsh industrial environments, and the color red is conventionally used to indicate stop, fault, or critical status in many automation setups. When paired with the appropriate light source and housing, it becomes a durable, interchangeable component within Siemens signaling columns for clear, immediate visual feedback on the shop floor.
